Hallopeau-type pemphigus vegetans is a rare form of pemphigus characterized by the development of vegetating lesions located mainly on flexural areas. A retrospective study was carried out of patients with diagnosis of pemphigus admitted at our Department (1988-2007). The three cases found to be Hallopeau-type pemphigus vegetans are described and a review of the literature is performed (Dermatol. Argent., 2011, 17(4): 294-300). Keywords: pemphigus vegetans, Hallopeau, Neumann.
